Application filed July '5, 1916. Serial no. 107,584.

constructed and arranged to be-interposed between the upper and lower members .of an automobile spring, and calculated to take up shock and jar and prevent injury to the spring when the upper spring memberis violently depressed to an undue extent as well as when the lower spring memberis suddenly forced upward, to a considerable extent. i

The invention in all of its details will-be fully understood from the following de- Figure 1 is a view, partly in elevation and.

partly in section, showing the working arran'gement, of my novel buffer construction.

Fig. 2 is a detail transverse section, taken through the buffer construction in the plane indicated by the line 2-2 of Fig. 1.

Similar numerals of reference designate corresponding parts inboth views of the drawing.

The chassis of the automobile is indicated by 1 in Fig. 1, and the axle is indicated by l ,'while 2 indicates an elliptical spring of the ordinary or any other suitableconstruction which is interposed between and has its upper and lower members clipped or otherwise suitably-connected with the chassis 1 and the axle 1 respectively, as illustrated in Fig. 1.. 1

My novel buffer is interposed between the upper and the lower members of the spring 2, and in the preferred embodiment of the invention the lower bar of the lower buffer section is clipped or otherwise connected 7 Specification of Letters Patent.-

Pat'entedFeb. 6, 1917.

with the .axle l pandthe upper bar of the upper buffer section is clipped or otherwise connected with the chassis 1; the connections.; being preferably, though not necessarily elfected by, the same clips that connectthe. members'of the spring 2.

Each o f' the bufier sections referred to is formed of metal,-and comprises an upper horizontal bar, a lower horizontal bar, and

upright bars or rods that connect the upper and lower bars. I

The upper bar 4 of the lower section is provided with apertures 5 which receive and guide the vertical bars of the upper section,

and the lower bar 4 of the upper section is provided with apertures6 which receive and guide the upright bars of the lower section. In addition to the upper and lower sections alluded to, my novel buffer comprises auxiliary, helical springs 8, and pads or cushions 7 of rubber, rubber composition or other resilient material. The auxiliary springs 8 are arranged in the vertical center of the buffer, and the upper spring 8 is interposed between the top bars 3 and 4: of the two sections, and is arranged at its ends in cups 9 or is otherwise held against lateral movement or displacement. The lower spring 8 is similarly held by cups 9 or other means carried on the lower bars of the two sections. The pads 7 are arranged and suitably secured on the opposed bars of the two sections which are movable vertically with respect to each other. It will also be noted that the upper bar of the lower bufier section is equipped with cushions 7 at its opposite sides, while the upper andlower bars of the upper section have cushions at theirundersides, and the lower bar of. the lower section has cushions on its upper side. It will also be noticed that the cushions are arranged in vertical series and in opposed relation, so that the buffer will have adequate cushioning capacity when the upper spring member is suddenly forced downward, and the lower spring member is suddenly forced upwardly, with the result that irrespective of the direction in which the thrust is imposed injury to the spring will be effectually prevented and at the same time the transmission of shock or jar in either direction will be precluded.

The springs 8 not only assist in cushioning the chassis 1, but they also serve to yieldingly hold the sections of the buffer in the normal position illustrated in Fig. 1 so that too free vertical movement of the buffer sections with respect to each other is prevented. This will be better understood when it is stated that on upward thrust of chassis, an axle, an elliptical spring interposed between and connected with the chassis and the axle, and a buffer construction interposed between and connected with the upper and lower members of said spring, and also connected with the chassis and axle and comprising lower and upper sections, each section having upper and lower horizontal bars and vertical rods connecting said bars, and the upper section having apertures in its lower bar receiving the verthe lower member of the spring 2, the lower tioal rods of the lower section, and the spring. 8 must be compressed before the pads 7 can come into contact, and this is also true of the upper springs 8, and again when the thrust is downward on the upper member of the spring 2, both springs 8 must be compressed before the pads 7 come into contact. From this it follows that generally un der normal conditions, the springs 8 will serve to prevent contact between the pads 7 and at the same time will enable the buffer sections to prevent injury to the main spring. When, however, an extraordinary thrust either upward or downward is imposed on the buffer and the opposed pads 7 are put in operation, the said pads will serve effectually to prevent injury to the spring 2 as well as to the springs 8 and the sections of the buffer.

It will be gathered from the foregoing that my novel buffer construction is simple and compact in construction and is well adapted to withstand the rough usage to which devices of corresponding character are ordinarily subjected. It will also be gathered that the buffer construction is susceptible of being readily applied to old and new automobiles.

While my bufler construction is designed particularly for use in combination with the upper and lower members of an elliptical spring, I would have it understood that the buffer construction may be used in other relations without involving departure from the scope of my appended claims.

Having described my invention, what I claimsand desire to secure by Letters-Patent, is:

1. A buffer construction comprising lower and upper sections, each section having upper and lower horizontal bars and vertical v rods or bars connecting said upper and lower bars, and the upper section having apertures in its lower bar receiving the vertical rods of the lower section, and the lower section having apertures in its upper bar receiving the vertical rods of the upper section; helical springs interposed between the upper bars of the two sections and the lower bars of said sections, respectively, and cushioning pads arranged in opposed relation on the horizontal bars of the sections.

2. The combination in a vehicle, of a lower section having apertures in its upper bar receiving the vertical rods of the upper section, helical springs interposed between the upper bars of the two sections and the lower bars of said sections, respectively, and cushioning pads arranged in opposed relation on the horizontal bars of the sections.

8. In means for the purpose described, the combination of an axle, amovable frame above and spaced from the axle, a lower spring connected with the axle, an upper spring connected with the frame, a connection intermediate the lower spring and the frame, and a connection intermediate the upper spring and the axle, whereby said springs are adapted by compression to ease the movements of the axle and frame with respect to each other.

4%. In means for the purpose described, the combination of an axle, a movable frame above and spaced from the axle, lower and upper coiled springs arranged in vertical alinement and spaced relation between the axle and frame; the lower spring being connected at its lower end with the axle and the upper spring being connected at its upper end with the frame, a connection intermediate the upper end of the lower spring and the frame, and a connection intermediate the lower end of the upper spring and the axle.

5. In means for the purpose described, the combination of an axle, a movable frame above and spaced from the axle, lower and upper spaced springs located between the axle and frame,a connection intermediate the lower portion of the lower spring and the axle, a connection intermediate the upper portion of the upper spring and the frame, a buffer section connecting the upper portion of the lower spring with the frame, and a buffer section connecting the lower portion of the upper spring with the axle; said buffer sections being each guided on the other.

6. In means for the purpose described, the combination of an axle, a movable frame above and spaced from the axle, lower and upper spaced springs located between the axle and frame, a connection intermediate the lower portion of the lower spring and the axle, a connection intermediate the upper portion of the upper spring and the In testimony whereof I have hereunto set frame, a bufl'er section connecting the upmy hand in presence of two subscribing wit- 10 per portilonfiof the lower spring Vfiiflil the nesses.
